to windows. In particular the invention is tight ships window.

Commonly, windows of this type comprise having a window opening therein.Behind the frame member and spaced therefrom a window-pane guideway isprovided. In the guideway, a frameless window-pane is slidably mountedand window-pane traversing means are provided for raising and loweringthe window-pane in the guideways. When the window-pane is in closedposition, the upper and side edges thereof are received in the guidewayand form a substantially weathertight connecis weathertight. I

tion therewith. These windows, however, are objectionable for the reasonthat in rough and stormy weather, even when the windowpane is in closedposition, water will enter 1 'between the frame member and thewindow-pane and also under the lower edge of the window-pane and entersthe structure below the window and subjects that structure to alternateperiods of dampness and dryness in accordance 'with the prevailingweather conditions.

By my invention, I am enabled to construct a ships window of this typewhich, in the closed position of the window-pane, employ a constructionwhich comprises a frame of rectangular window shape. In contact with theinner surface of this frame, the window-pane guideway is secured. Thus,there is no space hetween the frame and the guideway into which watermay enter. In order to prevent water and the like from entering underthe lower edge of the window-pane, I provide a jamming member which issecured to the lower end of the window-pane. The jamming member has aninclined surface which cooperates with a complementary surface formed onthe lower edge of the frame of window shape.

An advantage of my construction is the fact that the inclined surface ofthe jamming member acting against the inclined surface on the framemember forces the window-pane tightly against the guideway.

Other advantages of my invention will ap- 1930. Serial No. 439,871.

pear from the following particular description of one embodiment thereoftaken in connection with the accompanying drawings in which:

Fig. 1 is an elevation of a window constructed in accordance with myinvention;

Fig. 2 is an enlarged sectional elevation of the same taken on theirregular line 2-9. of Fig. 1; and

Fig. 3 is an enlarged fragmentary sectional elevation.

In the drawings, I have illustrated a window which comprises a framemember of window shape which is adapted to be secured to a wall 2 bymeans of machine screws 3. The frame member 1 is preferably made ofbrass .and has inwardly and outwardly extending flanges 1 and 5 whichdefine the Window opening therein. That portion of the inwardlyextending flange 2 which defines the bottom of the window opening isprovided with an inclined surface 6, the purpose of which willhereinafter appear.

To the inner surface of the frame member 1 there is secured arectangular frame of L-shape in cross section, one flange 8 thereofbeing secured to the window-shape frame member 1 and the other flange 9extending laterally therefrom. A guideway 10 is secured to this flange 9of the L-shape frame.

The 'uideway 10 is U'shape in cross section and is secured to the flange9 by means of machine screws 11 extending through the web of theguideway. The edges of one leg of the U-shape guideway contacts with theinardly extending flange 4r of the window shape frame member 1 along theupper and side edges of the window opening therein, the guidewayextending downwardly along the sides of the L-shape frame beyond thewindow-shape frame 1. The guideway is preferably lined with someflexible material 12 such as felt, and is adapted to guide a framelesswindow-pane 13 which is slidably mounted therein.

The window-pane 13 is adapted to be moved in the guideways to open andclose the window and for this purpose a transversing mechanism isprovided. The lower edge of the window-pane is secured in a clamp memher 14, a rubber lining 15 being interposed between the metal and thewindowpane. To the bottom of this clamp member 14, a member 16 issecured by means of machine screws 17. The member 16 extends downwardlyfrom the clamp 14% and is provided with lateral projections 18. Theselateral projections engage a collar 19 formed integral with the loweredge of a nut 20 which is threaded on a screw shaft 21. The nut is alsoprovided with an integral projection 22 which is adapted to be receivedin an opening in the member 16. Thus, movement of the nut along thescrew shaft moves the window-pane 13.

The screw shaft 21 is j ournaled at the upper end thereof in a thrustbearing secured to a cross member 23 which extends between the sides-ofthe L-shape frame member substantially at the center thereof. At thelower end, the screw shaft is j ournaled in the lower cross member ofthe L-shape frame member. At the upper end of the screw shaft, there issecured a beveled gear 2%. The beveled gear 24 meshes with a similargear 25 secured on the end of a transverse shaft 26 which is journaledat one end in a bearing bracket 27, and is journaled at the other end ina bearing bracket 28. A second beveled gear 29 is secured to theopposite end of the shaft 26 and meshes with a corresponding gear 30secured on the end of a short shaft 31 which is journaled in a bearingbracket The bearing brackets 28 and 32 are supported by an extension ofthe cross member which extends beyond the side of the L-shape framemember, the flange 9 of the L-shape frame member being cut away at thispoint. On the end of the stub shaft opposite the end to which thebeveled gear 30 is secured, a handle 83 is secured. Through this trainof mechanism, rotational movement of the handle 33 is transmitted to thescrew shaft 21 and rotational movement of the screw shaft raises orlowers the nut depending upon the direction of rotation of the screwshaft.

A jamming memberSt is secured against the outer surface of. thewindow-pane 13 adjacent the lower edge thereof. As shown on Figs. 2 and3, the jamming member is an integral part of the flexible lining 15which extends along the lower ed 'e of the window pane and has anextension along the outer surface of the clamping member. The jammingmember extension along the outer surface of the clamping member issecured to the side of the clamping member by a plate and machine screws35 which extend through the plate and into the clamping member. hejamming member is preferably made of some pliable material, such forinstance as rubber, and is provided with an inclined surface '86converging toward the S1f&C of the window-pane. This inclined surface iscomple mentary to the surface 6 formed on the lower portion of theinwardly extending flange l defining the window opening in theWindowshape frame member 1. When the windowpane is raised to the closedposition, the inclined surface 36 of the jamming member 34 cooperateswith the inclined surface 6 on the inwardly extending flange 4 of thewindowshape frame member 1 to exclude all manifestations of theelements, which would otherwise enter at this point. The jamming memberalso serves to press the window-pane against the flexible lining of theguideway, thereby making the window, in the closed position,substantially weathertight.

t is obvious that various changes may be made in the illustratedembodiment above particularly described by those skilled in the artwithin the principle and scope of my invention as expressed in theappended claims.
